p
確認

q
終了

Synergyインストール

現在Input Directorを利用中。
Linuxの端末も含めたいとなると、Synergyが有力なので試してみた。

・インストール時に聞かれる自動設定はしない。
・サーバー側、メイン画面でServerにチェック。
・サーバーを設定を開いて、ディスプレイの絵をドラッグし、クライアントのPC名を入力。
・クライアント側、メイン画面でClientにチェック。
・サーバーIPのところに入力。

これだけ。

Windows パーティション

基本的な操作は、
compmgmt.msc
か、直接、
diskmgmt.msc
から

パーティションサイズをピッタリにしたい場合、
例えば100GBにしたい場合、
102404MB(1024*100+4)
でピッタリ。

回復パーティーションの削除
diskpart
list disk
select disk n
list partition
select partition n
delete partition override

SRT100でIPv6の設定、サブセグメント構築

初期化

シリアルケーブルつないでTeraTermで接続できる。
漢字コードはShift-Jisに変更

初期IPアドレス
192.168.100.1

初期パスワード
doremi

非常用パスワード
w,lXlma

administrator
管理者切り替え

cold start
初期化

quit
終了

show config
設定一覧

save
保存

サブセグメント追加

試しに既存セグメント(192.168.11.0/24)に追加。

IPアドレスの設定は、
LAN2(192.168.11.100)
LAN1(192.168.12.1)

デフォルトゲートウェイは、
192.168.11.1

NAT(IPマスカレード)は、
LAN2に外側(192.168.11.100)、内側(自動)

DHCPは中止しておく。

IPv6設定

設定
ipv6 prefix 1 ra-prefix@lan2::/64
ipv6 lan1 address ra-prefix@lan2::1/64
ipv6 lan1 rtadv send 1 o_flag=on
ipv6 lan1 dhcp service server
ipv6 lan2 dhcp service client ir=on
dns server dhcp lan2

確認
show ipv6 address lan1
show status ipv6 dhcp

繋がったけど安定しなかったので中止。

Windows上にサーバー作成 Nginx/PHP/MariaDB/WordPress

以前は必要になるとXamppを使ってたけど、今回はNginx環境を手動で作ってみる。

Nginx

Windows用のzipファイルをダウンロードし解凍する。設定ファイルはもともとのコメント部を消して、とりあえずこんな感じ。

nginx-1.19.2/conf/nginx.conf

worker_processes  1;

events {
    worker_connections  1024;
}

http {

    include mime.types;
    default_type application/octet-stream;
    sendfile on;
    keepalive_timeout 65;

    server {
        listen 80;
        root html;
        index index.php index.html;

        location ~ \.php$ {
            fastcgi_pass 127.0.0.1:9000;
            fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
            include fastcgi_params;
        }
    }
}

worker_processes 1;

events {

worker_connections 1024;

}

http {

include mime.types;

default_type application/octet-stream;

sendfile on;

keepalive_timeout 65;

server {

listen 80;

root html;

index index.php index.html;

location ~ \.php$ {

fastcgi_pass 127.0.0.1:9000;

fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;

include fastcgi_params;

}

Nginxフォルダのパスに日本語があると起動しない場合があるので注意。

PHP

ダウンロードして解凍したら、phpというフォルダでnginxの中に入れる。
(nginx-1.19.2/php)

php.ini-development
をコピーしてphp.iniにし、
extension_dir=”ext”
extension=php_mysqli.dll
を追記する。

MariaDB

ダウンロードして解凍したら、mariadbというフォルダでnginxの中に入れる。
(nginx-1.19.2/mariadb)

nginx-1.19.2/mariadb/bin
の中にある、mysql_install_db.exeを実行すると、
nginx-1.19.2/mariadb/data
が作成され、my.iniも入っている。
(Nginxフォルダを移動したらmy.iniを修正しないと起動しない)

手動でDB作成等に使う場合、まずbinの中のmysqld.exeを起動。次にコマンドプロンプトからmysql -u root のような感じでログインできる。

・設定
nginx-1.19.2/mariadb/bin
に移動しmysqldを起動後、
mysql -u root
とするとログインできる。

mysql> set password = password(“1234”);

・データベース作成
mysql> create database wpd character set utf8;
(utf8を指定しないとWPのインストールでエラー)

起動・終了バッチ

start.bat

start nginx.exe
start /min php/php-cgi.exe -b 127.0.0.1:9000
start mariadb/bin/mysqld.exe

start nginx.exe

start /min php/php-cgi.exe -b 127.0.0.1:9000

start mariadb/bin/mysqld.exe

my.iniを自動で書き換える場合このような感じ

echo [mysqld] > ./mariadb/data/my.ini
set p=%~dp0mariadb/data
echo datadir=%p:\=/% >> ./mariadb/data/my.ini
echo [client] >> ./mariadb/data/my.ini
set p=%~dp0mariadb/lib/plugin
echo plugin-dir=%p:\=/% >> ./mariadb/data/my.ini

start nginx.exe
start /min php/php-cgi.exe -b 127.0.0.1:9000
start mariadb/bin/mysqld.exe

echo [mysqld] > ./mariadb/data/my.ini

set p=%~dp0mariadb/data

echo datadir=%p:\=/% >> ./mariadb/data/my.ini

echo [client] >> ./mariadb/data/my.ini

set p=%~dp0mariadb/lib/plugin

echo plugin-dir=%p:\=/% >> ./mariadb/data/my.ini

start nginx.exe

start /min php/php-cgi.exe -b 127.0.0.1:9000

start mariadb/bin/mysqld.exe

stop.bat

nginx.exe -s quit
Taskkill /f /im php-cgi.exe
mariadb/bin/mysqladmin.exe -u root -p1234 shutdown

nginx.exe -s quit

Taskkill /f /im php-cgi.exe

mariadb/bin/mysqladmin.exe -u root -p1234 shutdown

あるいは全て強制終了
(こうしないとプロセスが残る場合あり)

Taskkill /f /im nginx.exe
Taskkill /f /im php-cgi.exe
Taskkill /f /im mysqld.exe

Taskkill /f /im nginx.exe

Taskkill /f /im php-cgi.exe

Taskkill /f /im mysqld.exe

mysql.bat

mysqlのディレクトリに移動するためだけのバッチ

cd %~dp0mariadb/bin
cmd /k

1 2	cd %~dp0mariadb/bin cmd /k

WordPress

nginx-1.19.2\html\wp
にWordPressを解凍したので、ブラウザから、
http://localhost/wp
にアクセス。

DBの情報を入れて送信したところ、
サイトに重大なエラーがありました。
と表示されエラーになった。
(１度目のインストール)

・DBをリセット
フォルダを手動で削除せず、mysqlのコマンドからdrop databaseする。
そして再度create databaseする。

・wp-config.phpを削除
wp-config-sample.phpを複写し、名前をwp-config.phpに変更する。

wp-config.phpが存在しないと自動でwp-config.phpは作成されるが、ここでは手動でwp-config.phpを設定する。

wp-config.phpの以下の部分をtrueに変更する。
define( ‘WP_DEBUG’, true);

以下の部分にDB情報を記入する。
define( ‘DB_NAME’, ‘wpd’ );
define( ‘DB_USER’, ‘root’ );
define( ‘DB_PASSWORD’, ‘1234’ );

再度挑戦するが、
サイトに重大なエラーがありました。
と表示されるだけで、特にエラー内容は表示されない。
(２度目のインストール)

Nginxのログ(logs/error.log)
を確認すると、
Fatal error: Maximum execution time of 30 seconds exceeded
とあるので、
php.iniで下記の部分を30から120に変更
max_execution_time = 120
(３度目のインストール)

これでインストールできた。

LAN経由(外部)から見る場合、ファイアーウォールに新しい規則を追加する。
もしCSSが適用されていない場合は、
設定＞一般＞アドレス
をIPアドレスに変更してみる。
